Figure 4.

Clinician Dashboard homepage with four exemplar test patient cards. Each card presents on the left: the Heart Rate, Respiratory Rate, peripheral blood Oxygen Saturation (“O₂”), Blood Pressure, and Temperature; and on the right: the Notifications (disabled at this time), continuous Early Warning Score (disabled at this time), Level of consciousness, Steps and Posture. The patient name, Medical Record Number and location are shown at the top of each card. At the bottom of each card, the status of the wearables, including connectivity and battery status, can be observed (from left to right, the VitalPatch®, tablet, and Nonin icons are shown when present—such as in the first card). It can be noted that the upper left patient is “Starred” (by the active yellow star), with a VitalPatch® device connected, in range and with a remaining battery of 118 h; the tablet has a battery charged at 50% of capacity; and the Nonin device is connected to the tablet but has no battery left (0 h). The battery icon flashes in this case, to prompt for a change of batteries. The upper right patient had their last observation 3 months ago, showcasing the system's ability to keep the last patient state until they are discharged from the system (the Nonin also has no battery left in this case). The lower left patient has been pre-registered but the wearable devices have not yet been attached to the patient, as indicated by the lack of icons for the wearables, and thus no vital-sign data are available yet. The lower right patient has no “Patient, Name,” being identified only by the MRN in this case. The right-side Nonin icon is also greyed, representative of a Nonin pulse oximeter associated with the patient but out of range from the patient's assigned vHDU tablet. AVPU, Alert, Voice, Pain, Unresponsive scale; GCS, Glasgow Coma Scale; J-WD, John Radcliffe Hospital Ward Code; MRN, Medical Record Number.
